Lower the cover at the leisure centre (5)
I believe the answer is:
scowl
'lower' is the definition.
(scowling is a kind of lowering)
'cover at the leisure centre' is the wordplay.
'cover' becomes 'cowl' (cowling is a kind of covering).
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the leisure centre' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'cowl' after 's' is 'SCOWL'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for scowl that I've seen before include "Lower" , "Glare" , "dirty look" , "Angrily frown" , "Frown with displeasure" .)
